Wenn I choosed theme for this tourney I have imagine first prize like that. Doubtless the best problem. Mechanism with Pressburger King was otherwise used several times, but never to reach of such task. Congratulate author’s to this achievement!

a) h8 = Moose - hopper, but deflects 45° either way on passing over the hurdleb) h8 = Eagle - hopper, but deflects 90° either way on passing over the hurdlec) h8 = Sparrow - hopper, but deflects 135° either way on passing over the hurdled) h8 = Hamster - hopper, but deflects 180° either way on passing over the hurdlee) h8 = Grasshopper - hopper, don't deflects either way on passing over the hurdle

5 hoppers with diferent arrival square5 times move of hoppers from this same departure square5 times jumping of this same hurdle5 twins5 variations5 various mates from this same baterry5 times is white pawn frontal piece in baterry mates

Thematic very reach problem. Forsberg twins with various hoppers.
A little bit I mind using amount of technical dummies.

Special prize for most comprehensive theme handling. Everything here is themetic: count of pieces (5+5), count of solutions (5) also used fairy condition Take&Make is used 5-times. In case this problem existed befor tourney announcing I would us it as examle.

Very fancy exploitation of equihopper’s properties. Black with his first move enables jump of equihoppers every time on other square, in order it in second move create a hurdle to c4 and white then mates always with colorchanged piece. Prominency analogy.

The fairy condition “Fusil Turncoat” is rare:
When a piece captures (King included), it must return on the square occupied before, then changes of colour.

In the first variation it would be mate in Fusil after 1.g1=Q# but in Fusil turncoat white King becomes black after the capture of c2!
It also loses its character of royal piece so 2.Q:g7(wQg1) is not self check! The Queen of promotion will change three times of colour before to mate.
In the second variation, the promotion of white g7 Pawn in Knight provokes its return on g7 in black Knight then after a change of colour it is “sacrified” in e6 : the capture 3.f:e6(wPf7) provokes the return of black Pawn f7 in f7 …but in white Pawn! Follow an “orthodox” promotion in white Queen. This time it is the black Bishop g8 after a change of colour which will mate in f5.

5x unpinning5x way choice for white GN5x square enabling for a mate5x capturing of black Q

White GNd6 could mate but his own pawns constrain from this. BQ these squares in every solution releases and with his second move determinates choice of way for wGN.
Once again prominency analogy presented by author’s trio.

2x5 black pieces in the given position2x5 white pieces in the given position4x5 black moves + 4x5 white moves2x5 black pieces in the final position2x5 white pieces in the final position5 wK-moves5 bR-moves3x5 P-moves

In final position 14 pieces are blocked (Kh1, Rb8, Be8, Pa7,b7,d7,f7, Ka8 Re1, Rf8, Rg1, Pe2,g2,h2), whereas 6 are pinned (Qc8, Bd8, Sg8 by Pg2 and Bd1, Sb1, Sf1 by Pb7). In fact the work is based on the AntiCirce specific pinning of pieces by two Ps – g2 and b7 – ready to promote.
Mathematically expressed: the problem contains amount of thematic elements, but general artistic impression is obscure.
